POSIX atime, mtime, ctime

如果你包含一个完整的文字及其实际和预期产出,而不是REPL的碎块,就可能有所帮助。

import sys, os, stat, time

def get_times(p):
    s = os.stat(p)
    return ( 
        os.path.getatime(p),
        os.path.getmtime(p),
        os.path.getctime(p),
        s[stat.ST_ATIME],
        s[stat.ST_MTIME],
        s[stat.ST_CTIME],
    )

def main(p, delay=1):
    delay = float(delay)
    (a,b) = (1000000000, 1500000000)

    open(p, w ).close()

    print  initial: 
    print get_times(p)

    for t in [ (a,a), (a,b), (b,a), (b,b) ]:
        print
        print  test: , t
        os.utime(p,t)
        print get_times(p)
        time.sleep(delay)
        print get_times(p)

main(*sys.argv[1:])

我在我的10.4个系统上取得了这一成绩,有<条码>c d“$HOME” &&python 测试。 py tempfile 5 (系统系统故障2.3.6和MacPorts-030 2.6.4均得出相同结果(当然包括初始时间和 /m>):

% python /tmp/test.py tempfile 5
initial:

这似乎是合理的。 我想知道你们会怎样做。

我听到,Spotlight有时会因重新编篡改变了的档案而积极地重新启用atime。 我并不期望它重新编制只经过了假日/假日的文件,但我相信这样做是可能的。 在Spotlight(例如/tmp/testfile)未编入索引的地点,消除可能复杂化的Spotlight。

Date Created in Finder

(在Finder信息窗口中称为“混合:”)

如果安装了开发工具,你可使用<代码>/Developer/Tools/GetFileInfo>/code>,看家事科的创建情况。 我在每条<代码>印本上加上以下线:

sys.stdout.flush()
os.system( /Developer/Tools/GetFileInfo   + p)

我也修改了标题,以与你的初始描述相一致([(a,b)、(a)、(a)、(b)、(b)、(b)])。

结果是:

这似乎与你在Finder<>>>/em>上的Gefo之窗的意见一致。 我的解释(通过其他试验传播)是,建立爱阵设施。 日期按时段更新,但只是向后(不管向往)。 如果你想要更新爱幼学校的创造价值,那么你很可能不得不使用一种针对特定对象的软件来这样做。
